摘　　要：目的探讨残胃癌的淋巴结转移特点及外科治疗效果。方法回顾性分析1994年1月至2008年1月大连医科大学附属第一医院收治的42例残胃新生癌患者（研究组）和同期收治的56例胃上部癌患者（对照组）的临床资料。采用t检验、x^2检验分析相关数据，Kaplan—Meier法和Log—rank检验分析两组患者的生存率及淋巴结转移率。结果研究组和对照组患者的胃周围第1～3组淋巴结转移率相近，转移率为43％～61％，其差异无统计学意义（x^2=0．752，0．833，0．678，P〉0．05）；第7～9组淋巴结转移率分别为22％、18％、25％和46％、25％、30％，其差异有统计学意义（x^2=2．168，3．263，5．761，P〈0．05）；第10～14组淋巴结转移率分别为47％、36％、31％、20％、25％和33％、34％、19％、6％、0，其差异有统计学意义（x^2=3．225，1．883，3．945，4．137，6．823，P〈0．05）；第16组淋巴结转移率分别为0和23％；空肠系膜淋巴结转移率分别为27％和0。研究组和对照组患者总体5年累积生存率分别为38％和48％，两组比较差异有统计学意义（x^2=4．165，P〈0．05）。研究组和对照组根治度A、B患者的5年生存率分别为54％和57％，两者比较差异无统计学意义（x^2=0．622，P〉0．05）。结论残胃癌有其独特的淋巴结转移规律；应采取积极的外科治疗，对于改善患者预后有积极的作用。Objective To explore the characteristics of lymph node metastasis in gastric stump cancer and the efficacy of surgical treatment. Methods The clinical data of 42 patients with gastric stump cancer （test group） and 56 patients with primary cancer in the upper stomach （control group） who were admitted to The First Affiliated Hospital of Dalian Medical University from January 1994 to January 2008 were retrospectively analyzed. All data were analyzed by t test and chi-square test. The survival of the patients and lymph node metastasis rate were analyzed using the Kaplan-Meier method and Log-rank test, respectively. Results The metastasis rates of lymph nodes 1-3 of the test group and control group were similar （43%-61%）, with no significant difference between the 2 groups （ x^2= 0. 752, 0. 833, 0. 678, P 〉 0.05 ）. The metastasis rates of lymph nodes 7-9 of the test group and control group were 22% , 18% , 25% and 46% , 25% , 30% , respectively, and this was significantly different between the 2 groups （ x^2 = 2. 168, 3. 263, 5. 761, P 〈 0.05）. The metastasis rates of lymph nodes 10-14 were 47%, 36%, 31%, 20% and 25% in the test group, which were significantly higher than 33%, 34%, 19%, 6% and zero in the control group, respectively （x^2=3. 225, 1. 883, 3. 945, 4. 137, 6. 823, P 〈 0.05 ）. The metastasis rate of lymph node no. 16 was zero in the test group and 23% in the control group. The metastasis rate of jejunal mesenteric lymph nodes was 27% in the test group and zero in the control group. The accumulative 5-year survival rate of patients was 38% in the test group and 48% in the control group, and this was significantly different （x^2 =4. 165, P 〈0.05 ）. The overall 5-year survival rate of patients with radical resection was not significantly different between degree A （54%） and B （57%） （ x^2 = 0. 622, P 〉 0.05 ）. Conclusions Gastric stump cancer has a unique pattern in lymph node metastasis. Surgical resection is effective in improving the prognosis of patients wi
